Ignition Control Functions

When there is a call for heat, the combustion air blow- er starts to purge air from the combustion chamber. After the pre-purge, the igniter is energized. The stan- dard ignition module will lock out after failing to light four times or after losing flame three times during a single heat demand. To reset it, press and release the ESC/RESET button located on the user interface. The control will automatically reset after 1 hour. When in lock out, the control will run the blower for a 1 minute purge cycle. Turning off the power to the heater

WILL NOT reset the ignition module.

The optional single-try ignition module will attempt to light only one time before locking out. To reset it, press the ESC/RESET button on the user interface.

NOTE: Each ignition module is specific to a single model size. Care should be taken not to use a mod- ule intended for a different model size.
